where in nc are you aiming for, tom? the places i know that still need the most help are the truly rural (and mostly still cut off by damaged roads and other infrastructure), and some of the more densely populated urban spots, like the housing projects in asheville. asheville is still mostly weeks away from a functioning
water system, so any filtration type stuff could really help there. there are a number of mutual aid hubs developing, maybe you could plug in with one of them. will try to dig up contact info.
have not specifically heard about any homestead types that need help but will keep my ears open.
